Finder Sync
Modify the Finder’s user interface to express file synchronization and control.
Overview
Use Finder Sync to cleanly and safely modify the Finder’s user interface to express file synchronization status and control. Unlike most extension points, Finder Sync doesn’t add features to a host app. Instead, it lets you modify the behavior of the Finder itself.
Use this framework when you need to synchronize the contents of a local folder with a remote data source. Then provide visual feedback to the Finder by extending the FIFinderSync class and overriding appearance methods defined within the FIFinderSyncProtocol protocol.
